Title: Acoustic Sensing in Microfluidic Cell Keywords: acoustic sensing; fluid velocity measurements; microfluidic Abstract: In this work are presented early experiments for fluid velocity and pressure sensing in microfluidic cell, based on low frequency acoustic spectrum. Many of microfluidic cells and microfluidic chips internal properties could be observed only by numerical modeling. Some remote methods are applicable for contactless measurements inside the microfluidic cells channels. With advanced numerical procedures it can be reconstructed internal fluid flow properties. This paper considers measurements of acoustic signals, acquired over the fluid cell mixing chamber. Acoustic spectrum is correlated with fluid flow parameters as internal velocity and pressure. Results are verified by computational Fluid Dynamics (CFD) modeling of a microfluidic cell with known velocities and pressures. References Issue
